Vancouver, BC, July 3, 2015--(T-Net)--MacDonald, Dettwiler and Associates Ltd.(TSX:MDA), a global communications and information company, today announced that it has signed a contract for CA$7.4 million with Natural Resources Canada (NRCan).

MDA will provide In-Service Support to maintain and operate Canada's national ground station infrastructure at Inuvik, Prince Albert, and Gatineau.

MDA will also be the exclusive supplier of hosting services to a global base of satellite operators wishing to install and operate antennas at the Inuvik Satellite Station Facility (ISSF) for satellite control and data reception. The ISSF receives satellite information that is used for environmental monitoring, security and surveillance, and natural resource development.

For Canada, the ISSF enhances the country's ability to monitor the Arctic, increases social and economic development in the North, and provides Canadian and international users with expanded and more rapid access to Earth observation data.

The contract extends the strategic collaboration between MDA and Natural Resources Canada in service of the RADARSAT-2 and RADARSAT Constellation Mission programs.

The contract also positions MDA to supply satellite commanding and reception systems and services to other satellite operators at the ISSF.

Don Osborne, MDA's group vice president of Information Systems, said, "The expanded collaboration with NRCan creates numerous opportunities and enables both MDA and the government to benefit from Canada's continued investment in the North."

"Canada's satellite monitoring facilities contribute to environmental protection and help ensure the security and prosperity of all Canadians," said the Honourable Greg Rickford, Canada's Minister of Natural Resources. "We are pleased to collaborate with MDA to ensure continued access to critical satellite data and optimize development of the Inuvik facility."
